It’s Monday again and after too much pumpkin pie I finally have my adjustable shelf drill guide picture up. So the way this one works is you put a 3/16″ bit as deep as it will go in the drill and create a spacer block to control the drill depth just like a couple of posts ago. The trick is to keep the same side of the jig facing out while drilling all the holes. This jig is for these metal shelf pegs.
The problem with these is if you have a cabinet with shelves on either side of a 3/4″ divider and the holes are drilled all the way through the pegs bump into each other in the middle. That’s why the spacing on the left and right of the jig are different. The 1 1/4″ size was determined by the width of the drill I was using. Any closer to the back of the cabinet and it could not be drilled strait. Then the 1 5/8″ side moves the opposite hole over 3/8″. I usually end up making new drill guides whenever they are needed as they are usually too specific to reuse much.
